Patent DE-19621992-A1 (DE)
Inventor: BIONDI ANDREA
IPC: F16H53/06
Filed: 1996-05-31
Abstract: A conjugate cam mechanism 1 comprises a hydraulic lash adjuster having an eccentric lever 12 which is rotated by a hydraulic actuator 11 about axis 13a offset by distance e to an axis 6a of a follower element, eg roller 6. The actuator 11 pushes on lever 12, thereby moving roller 6 along trajectory T so that if play occurs (eg due to wear etc), between either rollers 6, 7 and their respective cams (see figs 1 and 2), the resulting clearance is eliminated. Oil is continuously supplied by a lubrication system (not shown) to chamber 18 via duct 20 and check valve 21. The check valve 21 prevents oil from leaving chamber 18 so that the roller 6 is constantly biased towards cam 3 which results in any clearance being compensated for immediately. As the cams are rotated about axis 5a they impart, via rollers 6, 7 which are mounted in a rocking support 8, a reciprocating motion to a shaft (see fig 1).

Title: Sputter cathode
Inventor: BAEHR MARTIN DR
IPC: C23C14/34
Filed: 1996-06-05
Abstract: The sputter cathode comprises a main body (2), a plane, plate-shaped target (11) comprising least one component, a magnet yoke (3) is located behind the target and having two oval or rectangular configurations, and rows of magnets ( 7, 7',..., 8, 8',...) arranged coaxially relative to one another in a plane parallel to the target plane, having different polarities and serving for generation of closed-configuration tunnels of arch-shaped field lines in front of the target. Blanks or appropriately configured blank constituents (12, 13, 14) of a magnetically conductive sheet are located in a plane between the target and the magnet faces directed towards target. Two of the blanks (12, 14) or blank constituents have a frame-like configuration, in which the sections joining the straight longitudinal frame sections have curved edge patterns differing from circular arcs. The width of the gap left between two adjacent edges with such patterns varies in an irregular manner.

Title: Hydrostatic=mechanical drive with load branching
Inventor: MEYERLE MICHAEL
IPC: F16H47/04
Filed: 1996-06-27
Abstract: The hydrostatic-mechanical drive consists of a hydrostat transmission with a first hydrostat unit (A) of adjustable volume and a second one (B) of constant volume. There is a load branching device with adding planetary transmission (37, 37a). The load branching transmission has a differential transmission (15, 58) which serves as an axial differential, for use with a front-wheel-drive vehicle. It is axially offset from the drive shaft (16) and is driven via intermediate members (10-14). The hydrostat transmission should preferably be a common structural unit in the form of a compact transmission.

Title: Semiconductor memory device for DRAM with self refreshing mode
Inventor: TSUKUDE MASAKI
IPC: G11C11/408
Filed: 1996-07-23
Abstract: The apparatus includes a memory field provided with matrix formed memory cells, an address labelling circuit (41), and a refresh execution circuit to execute a data refresh of memory cells corresponding to a word line. Also provided are two signal production circuits and a word line driver circuit. The word lines of the memory field are split into several groups with each word line corresponding to a row of cells, with bit line pairs being provided for the columns. In the refresh mode, an upper address is allocated to each group and an under address is allocated to each word line in each group.  The address labelling circuit reacts to a clock circuit at the setting of a self refresh mode with each following label of each under address belonging to an over address and then with labels of each under address belong to another over address. One signal production circuit (1-8), provided with each corresponding over address, outputs a group selection signal in response to the label of each over address. The second signal producing circuit outputs a corresponding word selection signal in response to the label of an under address. The word line driver brings a word line corresponding to the group and word line selection signals into an active state to bring the refresh circuit into an active state.

Patent DE-19634305-A1 (DE)
Title: Fire stop for ventilation duct
Inventor: SCHULTE GUENTER
IPC: A62C2/18
Filed: 1996-08-24
Abstract: The fire stop (18) moves vertically in a gap (17) in a double-walled sector of the duct (12). It is held open at normal temperatures, connecting two line sectors, but moved down at a higher temperature to close off the sector. It is held in the gap between two metal sheets curved to match the duct, and is similarly curved so as to be held to one sector until moved down to close off the section of a branch duct run radially off the main one. The movement of the stop is effected by a fusible solder mass (19) or bob which melts between 60 deg C and 80 deg C. The fire stop is made of a fireproof material of sufficient thickness to prevent the fire spreading from the main to the branch duct, and can also be made of sheet metal, specifically coated on one or both sides with foam swelling under heat, assisted by foam spread round the inner wall of the branch duct so as to swell under heat and close off the connection.

Title: Method and appliance for determining sensitivity of internal combustion engine methane sensor
Inventor: SCHENK RENE
IPC: G01R31/28
Filed: 1996-09-07
Abstract: The method involves a heatable methane molecule detecting probe electrode which generates a voltage which is a measure of the methane concentration. The voltage (U) generated by the probe is briefly short circuited. The resultant recovery voltage characteristic as a function of time is then measured and from the characteristic a conclusion can be on the sensitivity of the sensor is reached.  This conclusion can be on the basis of the time (time constant t) taken for the voltage to recover to a specific value. This measurement can be repeated and the average value of the time constants used.

Patent DE-19748270-A1 (DE)
Inventor: CHOI YOO JIN
IPC: G02F1/1337
Filed: 1997-10-31
Abstract: A liquid crystal display in which surface alignment treatment is applied to both substrates but a pre-tilt treatment to only one of the display substrates. The pre-tilt treatment is used to create multi-domain regions which change the liquid crystal director orientation within a single display region. Optical, rubbing or oblique deposition techniques may be used to define the pre-tilt sub-domains. The liquid crystal is preferably a twisted nematic containing chiral dopants. Single domain devices exhibit anisotropic optical variations that are noticeable when viewing such displays at different angles. One advantage of this multi-domain device is that this angular degradation may be eliminated or reduced. Another advantage is that by only applying a pre-tilt treatment to one substrate the number of manufacturing steps is reduced.
